Step 3
Describe other properties of poly(chloroethene) that make it suitable for gutters and drainpipes.
Answer
Poly(chloroethene) is durable and resistant to corrosion, which protects against rainwater damage. Additionally, it is lightweight, making it easy to install and handle. Its resistance to weathering ensures longevity, and it can be easily shaped into various forms.
Step 4
Discuss the advantages and disadvantages of each disposal method, and explain which disposal method should be used for plastic bottles.
Answer
Landfill disposal is often the easiest method but can lead to pollution and takes up space. Burning waste can generate energy but releases toxins into the atmosphere. Recycling conserves resources and reduces waste but requires an efficient system and participation. For plastic bottles, recycling is the preferred method as it minimizes environmental impact and reduces the need for new plastic production.
